hi all - is there any quick way to INCREASE the number of default login attempts from four to 10 for all present and future sites?

i have a multisite installation with 50+ sites -- i hope i dont have to go through all of these individually and change the values ! even if i have to do it in mysql its better than nothing, unless limit-login-attempts is using some serialized values which tend to be much harder to change.

it seems there is an incompatibility using limit-login-attempts with using SI-Captcha in that when you log out, you immediately "loose" one of your chances to log back in.
